7.1 Overview
Troubleshooting involves responding to error messages, primarily displayed by the HVC. Error messages
that may occur on the transmitter's local display are fairly self-explanatory and intuitive. However, this
section covers the diagnostic messages that indicate critical conditions. Other than the critical conditions,
additional detail is not provided. If you require assistance, contact your distributor or Honeywell
Technical Support. All other messages are covered by the Honeywell Versatilis Configurator User
Manual, #34-ST-25-70.
7.2 Critical Diagnostics Screens
When a Critical Diagnostic is present in the transmitter, the advanced display will show one or more of
the screens pictured in
displayed between the user-defined operator screens. A description of the diagnostic conditions is given
Table 22,
along with suggested actions for resolving the problem.
